My first plane was an LT-40 ARF. It survived getting me trained and still flies great. I've heard the kit version is very good.

Although there's not much money to be saved (if any) building a kit, its tons of fun (for me anyway).

The LT-25 kit goes together nicely and flies well. It has a GMS 32 engine and the plane is somewhat overpowered. I pulled it through a loop the other day at about 1/3 throttle.
Level flight can be maintained just above idle. Should have gone with a 25 engine.

I also built (and have yet to maiden) a 4*60. I've seen this plane refered to as a "low wing trainer"

So, I'm partial to SIG I guess but I'm sure the other recommendations made here are excellent as well.
